[0038] The embodiment of the present application provides a water leakage warning device for a water pump, which can improve the problem of inconvenience in operation caused by the need to replace cotton swabs in existing warning devices.

[0039] refer to Figures 1 to 5 , a water leakage warning device for a water supply pump comprises: a shell 1, a warning switch 2, an alarm 3, a trigger mechanism 4 and an elastic support 5. A support plate 11 for installing a water supply pump 6 is arranged in the shell 1. The warning switch 2 is arranged below the support plate 11 and fixed to the shell 1. The alarm 3 is arranged in the shell 1 and connected to the warning switch 2. Specifically, the alarm 3 is arranged on the outer wall of the shell 1. The trigger mechanism 4 comprises a water tank 41, which is slidably arranged between the support plate 11 and the warning switch 2 up and down, and the water tank 41 is used to receive the leaking water of the water supply pump 6. The elastic support 5 is arranged between the water tank 41 and the shell 1, and the elastic support 5 is arranged to keep a distance between the water tank 41 and the warning switch 2 when the water supply pump 6 is not leaking. During use, when the water pump 6 is not leaking, the weight of the water tank 41 is relatively light, and the elastic support 5 can support the water tank 41 to keep it at a distance from the early warning switch 2. When the water pump 6 is leaking, the weight of the water tank 41 increases, making it impossible for the elastic support 5 to continue to support the water tank 41. The water tank 41 will slide downward until it presses the early warning switch 2. At this time, the early warning switch 2 controls the alarm 3 to sound an alarm.

[0040] In some embodiments, a drainage hole 12 may be provided on the side or bottom of the housing 1 to drain water when there is leakage inside the housing 1, so as to prevent the leakage water from accumulating inside the housing 1 and affecting the downward movement of the water tank 41. In this embodiment, the drainage hole 12 is located on the side of the housing 1 near the bottom.

[0041] In some embodiments, the trigger mechanism 4 further includes a funnel 42 and a hose 43, the funnel 42 is fixed to the bottom of the support plate 11, and the lower end of the funnel 42 is connected to the water tank 41 through the hose 43. In this way, the leaked water can be collected by the funnel 42 and collected in the water tank 41, which is conducive to reducing the leaked water falling into the bottom of the housing 1. It should be understood that in the specific setting, the funnel 42 can be connected and fixed to the support plate 11, or it can be directly fixed in the housing 1.

[0042] In some embodiments, a drain hole 411 is provided at the bottom of the water tank 41, and a piston 412 is provided in the drain hole 411. That is, after the early warning, the water in the water tank 41 can be drained by pulling out the piston 412 for subsequent use.

[0043] In some embodiments, the drain hole 411 is located on a side of the door panel 13 of the water tank 41 facing the housing 1. In this way, when the operator opens the door panel 13 for inspection, the piston 412 can be pulled out to drain the water, which is conducive to improving the convenience of operation.

[0044] In some embodiments, the piston 412 includes a first plug 4121 and a second plug 4122, the second plug 4122 is connected to both sides of the first plug 4121, and the insertion length of the second plug 4122 is less than the insertion length of the first plug 4121. In other words, in the process of pulling out the piston 412, the second plug 4122 can be pulled out first, that is, only part of the piston 412 can be pulled out to achieve drainage. Therefore, in actual use, it is not necessary to completely pull out the piston 412, so that the piston 412 can be easily inserted back into the drainage hole 411.

[0045] In some embodiments, a plug-in assembly is provided between the piston 412 and the door panel 13, and the plug-in assembly is configured to be able to pull out the piston 412 when the door panel 13 is opened to drain water. Compared with manually pulling out the piston 412, this can improve the convenience of operation. It should be understood that in a specific configuration, the door panel 13 can be a single-opening door or a swing door, etc.

[0046] In some embodiments, the door panel 13 is a swing door. The plug assembly includes a connecting plate 131 and a guide rod 413. The connecting plate 131 is slidably disposed on the inner side of the door panel 13, and the connecting plate 131 is provided with a guide groove 132. The guide groove 132 includes a first guide section 1321 and a second guide section 1322 connected to each other. The first guide section 1321 is consistent with the moving direction of the door panel 13, and the second guide section 1322 gradually approaches the water tank 41 in a direction away from the first guide section 1321. The guide rod 413 is connected to the piston 412 and is slidably disposed in the guide groove 132. Specifically, when the door panel 13 is closed, the piston 412 is in an inserted state, and at this time, the guide rod 413 is located in the second guide section 1322 and is far away from the door panel 13. When the door panel 13 is gradually opened, the guide rod 413 moves along the second guide section 1322 toward the door panel 13, and at the same time, the guide rod 413 drives the piston 412 toward the door panel 13, until the guide rod 413 slides into the first guide section 1321, and the piston 412 is pulled out (the second plug 4122 of the piston 412 is pulled out). Of course, when the door panel 13 is gradually closed, the guide rod 413 can be driven to slide in the opposite direction, so that the piston 412 is inserted into the drain hole 411. It should be understood that since the connecting plate 131 is slidably arranged on the inner side of the door panel 13, the connecting plate 131 can move up and down together with the water tank 41 during specific use.

[0047] In some embodiments, the elastic support 5 includes an elastic member 51, and the elastic member 51 is disposed between the water tank 41 and the bottom of the housing 1. Specifically, the elastic member 51 can be a spring, which can support the water tank 41 under the action of its own elasticity to keep it spaced from the early warning switch 2, and can also accumulate potential energy when the water tank 41 increases weight and moves downward, and the potential energy can reset the water tank 41 after it is drained. In addition, the elastic member 51 can also consume the impact force of the water tank 41 in the process of continuing the potential energy, thereby playing a buffering role on the water tank 41. It should be understood that in order to ensure the supporting effect, in the specific setting, the number of elastic members 51 can be multiple, and the multiple elastic members 51 are supported at different positions around the water tank 41.

[0048] In some embodiments, the inner wall of the housing 1 is provided with a slide groove 14, and the elastic member 51 is located in the slide groove 14. This arrangement enables the slide groove 14 to limit the spring, preventing the elastic member 51 from tilting or bending outward when compressed, thereby affecting its supporting effect. It should be understood that in order to enable the elastic member 51 located in the slide groove 14 to play a role in supporting the water tank 41, in a specific arrangement, the water tank 41 can be provided with a slide rod 414 that can extend into the slide groove 14 and contact the upper end of the elastic member 51.

[0049] In some embodiments, the elastic support 5 further includes a sleeve 52, a first connecting column 53 and a second connecting column 54. The sleeve 52 is sleeved on the elastic member 51, and the upper end of the sleeve 52 abuts against the bottom surface of the water tank 41. The first connecting column 53 is sleeved in the sleeve 52 and connected to the upper end of the elastic member 51, and the first connecting column 53 can rotate circumferentially relative to the sleeve 52. The second connecting column 54 is sleeved in the sleeve 52 and connected to the lower end of the elastic member 51 (located between the elastic member 51 and the bottom of the housing 1), and the second connecting column 54 can rotate circumferentially and move axially relative to the sleeve 52. In addition, the inner wall of the sleeve 52 is provided with a spiral guide groove 541, and the second connecting column 54 is provided with a slider 521, and the slider is located in the spiral guide groove 541 and slides with the spiral guide groove 541. That is to say, in specific use, the elastic support 5 contacts the water tank 41 through the sleeve 52. When the water tank 41 moves downward, the sleeve 52 moves downward along the axial direction of the second connecting column 54. At the same time, the second connecting column 54 rotates circumferentially relative to the sleeve 52, and the sleeve 52 squeezes the elastic member 51 through the first connecting column 53 and the second connecting column 54 to shrink it. In this process, there is friction between the spiral guide groove 521 and the slider 521, so that the impact force of the water tank 41 can be further consumed, thereby improving the buffering effect on the water tank 41. It should be understood that in specific settings, in order to achieve compression of the elastic member 51, the first connecting column 53 should be axially fixed relative to the sleeve 52.

[0050] In some embodiments, a groove 4141 is provided on the side of the water tank 41 (sliding rod 414), and a flange 531 is provided on the side of the first connecting column 53, and the flange 531 is located in the groove 4141 and is in clearance fit with the groove 4141. This arrangement can achieve axial fixation of the first connecting column 53 relative to the sleeve 52, and allow the first connecting column 53 to rotate circumferentially relative to the sleeve 52. With respect to providing stoppers at both ends of the first connecting column 53, this can facilitate the processing and installation of the first connecting column 53.

[0051] The water leakage warning device for the water supply pump provided in the embodiment of the present application has the following working process: when the water supply pump 6 leaks, the leaked water falls from the support plate 11 and is collected by the funnel 42 and stored in the water tank 41. As the weight of the water tank 41 increases, the sleeve 52 begins to move downward along the axis of the second connecting column 54, and squeezes the elastic member 51 through the first connecting column 53 and the second connecting column 54 to shrink it until the water tank 41 falls on the warning switch 2, and the warning switch 2 controls the alarm 3 to sound an alarm. After receiving the alarm, the operator opens the door panel 13 of the housing 1 for inspection. At the same time, the door panel 13 pulls out the piston 412 through the plug-in assembly during the opening process, so that the water in the water tank 41 is discharged. As the water level in the water tank 41 drops, the elastic member 51 drives the water tank 41 to reset through the first connecting column 53 and the sleeve 52 under the action of its own elastic force. After the inspection and maintenance work is completed, the operator closes the door panel 13 of the housing 1. During the closing process of the door panel 13, the piston 412 is inserted back into the drain hole 411 of the water tank 41 through the plug-in assembly.

[0052] The water leakage warning device for the water pump provided in the embodiment of the present application uses a water tank 41 that can slide up and down to trigger the warning switch 2. Compared with the method of using a cotton swab to trigger it, it is only necessary to drain the water in the water tank 41 during the maintenance process before continuing to use it. There is no need to dry or replace the water tank 41, and the operation is simpler and more convenient.
